Global temperature and recent flat lining

Much is said about how, despite global warming, the average global temperature has pretty much flat lined over the last decade.

And yet, as the Arctic warms up very rapidly, it’s affecting the Jetstream. This phenomena exists as a result of the differential between the cold air to the north, and the warm air to the south, It defines the boundary between the two.

As the Arctic warms, the Jetstream is becoming erratic. This erratic behaviour includes a tendency to move further south than would historically be seen as normal. In doing so, it draws cooler air further south than normal, hence the current cold temperatures across Europe, relatively much colder for the time of year than the Arctic is warmer.

This Arctic air is cold only by European standards. In fact, as Arctic air, it’s warmer than historically would be the case. Nonetheless, this results in a drop in the average temperatures recorded across Europe, and the whole of the northern hemisphere, including the Arctic, giving the impression of a moderated rate of global warming.

Is it not possible then that global warming is resulting in a dramatic regional rise in certain zones, namely the Arctic, which is resulting in a drop in temperatures in temperate zones, that’s in turn generating average global temperatures that appear to be flat lining even though a dramatic shift is taking place. Average temperatures rise over a specific region – the Arctic – which results in a relatively small but very noticeable drop in neighbouring areas. But what’s in fact happening is a cataclysmic rise in the Arctic, and a relatively modest drop elsewhere, but over a larger area. Which, because the Arctic is smaller than the temperate zones being affected, gives the impression that temperatures over all are not rising.

The upshot being that, as these recent norms become built into the average, as the Arctic warms further, we’ll see a sudden large jump in average temperatures in the northern hemisphere in a few years time, that will at least compensate for the recent moderation in temperature rise.
